What is your CYA level?

I doubt you have issues with CH as the powder is cal hypo. But the pucks are trichlor.

You can use some of the pucks if you like. Or keep them for when you are going to be away from the pool for more than a few days and use them then.

The Max 70 is calcium hypochlorite. So it adds chlorine and calcium to your water. The chlorine is used up, but the calcium stays in your water. I am guessing (no water test data to go on) that CH in your water is not an issue. As Cal Hypo will add calcium to your pool.

I don't at the moment as I didn't do that test since my pool is vinyl. But I can complete one.

what readings would make it ok to use the HTH
